A uterus implanted into a woman from a living donor resulted in a successful birth in Dallas last month, the first such delivery in the United States.

Doctors at Baylor University Medical Center believe the milestone lead to fertility for thousands of women unable to become pregnant, the Dallas Morning News reported. Nicknamed "Baby Number Nine," the child follows only eight successful births using the process worldwide.

The mother, born without a uterus, received a womb and cervix last September as part of an ongoing Baylor study, per ABC News. Her condition, known as absolute uterine factor infertility, affects 1 in 500 women with non-functioning or non-existent uteruses, according to the network.

The birth offers hope to other seven women who've received transplants in the study, doctors told ABC. Four of those transplants remain in process, while three failed and one recipient is currently pregnant.

Once transplanted, each recipient can deliver two babies before the organ must be removed, the Morning News reported. A mother can receive a previously frozen embryo as soon as 12 months after her transplant.

But such transplants wont' likely emerge as a mainstream practice soon, according to the Morning News.

The procedure carries an massive price tag, requiring a team of specialists and surgeries for both donor and recipient. Doctors are still learning about the risks posted for donors and recipients, too.
